Partially revert Python 2.7 removal

This partially reverts commit 1bd49cf.
Since I modified the templates which `tox -e bootstrap` uses, I couldn't
trust the generated files anymore. So I reverted my changes and
re-generated the files. The only change I left in was the removal of
Python 2.7 from `setup.py` as it seems that this file doesn't get
touched by tox.
